AbstractThis work aims to redesign the large regions of Brazil based on agglomerations of municipalities with similar socioeconomic characteristics. Based on data from the last two censuses, 2000 and 2010, a matrix of 41 socioeconomic variables was selected for each one of the Brazilian municipalities. Then, the size of this matrix was reduced using the principal component analysis (PCA) method. The main components were selected to compose the algorithm of hierarchical agglomeration that defined the municipal clusters. The results of the agglomeration indicated the existence of eleven regions of municipalities for the year 2000 and ten regions for the year 2010, showing that the current political‐administrative map of the regions does not represent the junction of cities that maintain a relation of homogeneity.

Abstract: Successive reforms in the Common Agricultural Policy (CAP), enlargements of the European Union (EU) and pressures in the public budget increase the need for empirical studies to assess the role of subsidies in shaping firms' performance and, hence, to support policy-makers decisions and decision-making in the productive sector. This paper assesses whether subsidies affect the technical efficiency of 1,943 Portuguese agribusiness firms over 2007-2015. By applying stochastic frontier models and fixed-effects models, to calculate the average efficiency of these firms, the results show different effects of subsidies among agribusiness sectors. The stochastic frontier model revealed that the subsidies have a positive and significant impact on the technical efficiency of three sectors, animal production, manufacture of food, and manufacture of paper. Further, except for firms in the forestry and logging sector, Portuguese agribusiness firms had higher average efficiency levels when subsidised, which provides evidence that subsidies could be important and contribute positively to the technical efficiency of Portuguese firms.

O presente artigo teve por objetivo analisar o comportamento, entre 2007 e 2017, e a previsão da taxa de inflação no Brasil. Os indicadores econômicos influenciam diretamente nas decisões estratégicas das empresas públicas e privadas, e, neste contexto, é fundamental avaliar os dados, na tentativa de prever os comportamentos futuros de tais números. Os resultados estimados por meio do Modelo SARIMA podem auxiliar em futuras eliberações, pois, para a taxa de inflação brasileira, sua eficiência aponta 95% de acerto na tendência relativa aos próximos anos. A estimativa de previsão, utilizando o modelo sazonal, prevê um aumento da taxa de inflação para os próximos anos, seguindo uma provável retomada de crescimento do Brasil.
